Document Type and Number:
Japanese Patent JP7055600
Kind Code:
B2
Abstract:
The present invention belongs to the technological field of the reduction of noise produced by hermetic compressors, such as those used in cooling systems of household appliances. The acoustic filter (1) of the present invention comprises an inlet duct (2), an outlet duct (3) and at least one main chamber (4A), wherein the inlet duct (2) comprises a refrigerant fluid inlet (5) and a refrigerant fluid delivery end (6), wherein the refrigerant fluid delivery end (6) is opposite to said refrigerant fluid inlet (5) and it is capable of guiding the refrigerant fluid to the main chamber (4A); the outlet duct (3) comprises a refrigerant fluid outlet (7) and a refrigerant fluid collection end (8), wherein the refrigerant fluid collection end (8) is opposite to said a refrigerant fluid outlet (7) and it is capable of guiding the refrigerant fluid from the main chamber (4A) to said fluid outlet (7). The filter (1) comprises a resonator chamber (9) arranged adjacent to the inlet duct (2) and adjacent to the main chamber (4A), wherein the resonator chamber (9) and the inlet duct (2) are fluidically connected by means of at least one resonator tube (10A, 10B, 10C) and the resonator chamber (9) is separated from the main chamber (4A) by means of a sealing wall (11).
